He has already issued a health warning after posting videos of himself eating raw chicken breasts with raw eggs and smoothies.
But now the infamous Instagram user’s rawmeat project is back – and this time with a daily diet of raw testicles sourced from a bull.
The unnamed man, who has 150,000 Instagram followers and is from Florida, says the “experiments” are “for science” and “to boost testosterone.”
In one clip, which has more than 38,000 likes, he is shown eating an entire testicle before washing it down with a cup of blood. In another, he adds lettuce and tomato to a burger bun next to the testicle, creating a “ball burger.”
According to the content creator, his unlikely meat choice tastes like “a scallop that has been sitting in ground beef for six days.”
The person – known as John and appears to be from the US – says he consumes the testicles ‘for science’ and to find out if they increase his testosterone
He is now seven days into his ‘experiment’, which follows eating a raw chicken breast a day for 67 days, which he did until March this year
He is now seven days into the ‘project’ and is expected to continue until he becomes unwell.
The man first attracted attention earlier this year with his raw chicken project, which lasted 100 days.
In it, the man put raw chicken breasts in smoothies, on pizza – and washed down a chicken breast with a cup of raw eggs and orange juice.
Two years ago he did another experiment, eating raw meat at Whole Foods every day for 200 days. Ultimately, he ended the test because he was “bored.”
Instagram users have reacted to his posts with horror, calling his experiment “nasty” and “extremely rude.”
Experts are warning people against eating all forms of raw meat due to the risk of contamination with bacteria such as salmonella – which can cause stomach pain or, in severe cases, blood poisoning if the bacteria spreads to other parts of the body.
Four hundred and twenty Americans die from the bacteria every year, statistics show, while 1.35 million people are infected and 26,500 are hospitalized.
The CDC says whole cuts of meat should be cooked to at least 140 degrees Fahrenheit before consumption to kill any dangerous bacteria lurking inside.
The man has now reached day seven of his new diet and claims his energy levels are ‘solid’ and he has been able to play basketball daily.
The testicles weigh about 1 pound each, he said, and cost $20, while the man bought them locally. He described the testicles as “a scallop that has been in minced meat for six days.”
He first started documenting his raw meat consumption last year after suffering an acne breakout, which he said was alleviated by switching to raw foods.
After sharing videos of himself eating a raw chicken breast every day for 100 days, the experiment ended in March this year.
Revealing his experiment online, the individual wrote: ‘We are always told that organ meats, especially testicles, will take you to the next level.
‘How could eating a cow’s balls not give you huge balls yourself?
‘This is the science we want to test here. I’m going to eat meatballs and stay on top of many aspects of how I feel physically and mentally on a daily basis. I will update if my energy is crazy or if my pee gets bigger etc.”
Some users suspect the experiment is a parody, although this has not been verified.
People have eaten cooked anima; testicles for centuries, with the organs prized as a great source of protein and nutrients – and giving rise to dishes like Rocky Mountain oysters in the US and testicle goulash in Serbia.
More recently, some online influencers – such as ‘The Liver King’, famous for his raw meat diet – have posted videos of themselves eating raw testicles online, claiming it has health benefits and can boost testosterone levels.
But there is no scientific evidence that this is true.
